does anybody have any experience with the Vortex scope rings? I'm talking about the regular rings. I bought a PST 4-16 and I am wanting to get a solid set of rings without spending a butt load of money. I did save $120 on the scope, so that frees up some cash, but still...you know how it is. I've heard the Weaver tactical rings are good. What about the vortext precision matched (a bit pricey though)? What do you all suggest?
